**Damon**, Saturday, March 5, 2011 at 7:22pmFind the area of the surface of the water when water is 3 feet from the tip (A =pi r^2) where r = (2/5)(3)

dh (A) = dV

dh/dt = (1/A)(dV/dt)

but dV/dt is given, 3/2 ft^3/s

**Damon**, Saturday, March 5, 2011 at 7:41pmr = 6/5

pi r^2 = pi (36/25)

dh/dt = 25/(36pi) * 3/2

= 25 /24pi

agree
